Abstract

Abstract: The composite targets made of bulletproof fibers，SiC/Al composite material and ceramics in which the aerogel is an interlayer were tested, and the anti-bullet performance of composite structure with aerogel interlayer were studied. The results show that, when the aerogel is combined with bulletproof fibers, the aerogel interlayer could improve the anti-bullet performance of composite target because the deformation of bulletproof fibers is greater due to the low strength of aerogel interlayer. Thus the energy absorption capacity of composite targets improves significantly, and the non-penetrability damage of projectile can also be prevented. When the aerogel is combined with SiC/Al composite material, the anti-bullet performance of composite target improves slightly. The aerogel interlayer could improve the integrality of composite material faceplate after ballistic experiment obviously. When aerogel is combined with ceramics, ceramic faceplate may be bent due to the insufficient support of the aerogel interlayer, resulting in the decrease in the anti-bullet performance of composite target.

Key words: mechanics of explosion, aerogel, interlayer, composite structure, anti-bullet performance
